"The username violates our guidelines"

Yes as we have been saying, it's some software bug regarding old accounts. Nothing on purpose or anything.

Nope. Microsoft and Facebook discriminate against all. I get it too. My gf got blocked by facebook for spamming because she said she liked a friend's recipe. YouTube just deletes your comments. Copy you YouTube comment to clipboard before posting. Wait a minute. Then edit to add a period. If you get =an error that means google deleted you comment. Paste again, and play with wording. After a few dozen tries you might get posted. For example, replace the word white with misspelling of caucasian. Stuff like that. They are all idiots.

People think it only conservatives because Dems too stupid to be grilling them on thier stuff being censured when they have them before congress...plus conservatives do lie more.

I definitely think it has something to do with microsoft not being able to handle multiple platforms. Not a big deal, but I doubt my real name violates much of anything. I'm getting my xbox screen name when posting these comments, but that's modern compared to msn and hotmail

Same thing here, I highly doubt I offended anyone with my msn account, I can't even remember posting a comment. Maybe in the eighties or nineties

Thank you very much for the detailed explanation on how to solve this bug. As for suggesting this may not occur on a desktop with Edge browser, yes it's happening to me in this scenario.
